EEE 802 1x and Extensible Authentication Protocol EAP to authenticate wireless clients using an external RADIUS database WPA2 reduces the number of key exchange messages from six to four CCMP 4 way handshake and shortens the time required to connect to a network Other WPA2 authentication features that are different from WPA include key caching and pre authentication These two features are optional and may not be supported in all wireless devices Key caching allows a wireless client to store the PMK it derived through a successful authentication with an AP The wireless client uses the PMK when it tries to connect to the same AP and does not need to go with the authentication process again Pre authentication enables fast roaming by allowing the wireless client already connecting to an AP to perform IEEE 802 1x authentication with another AP before connecting to it Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA At the time of writing the most widely available supplicant is the WPA patch for Windows XP Funk Software s Odyssey client The Windows XP patch is a free download that adds WPA capability to Windows XP s built in Zero Configuration wireless client However you must run Windows XP to use it NET NBG4115 User s Guide Appendix D Wireless LANs WPA 2 with RADIUS Application Example To set up WPA 2 yo
